Question

what must be added to -3/8 to get 5/16 ?

Answer 1

Answer:

$\frac{11}{16}$

Step-by-step explanation:

$-\frac{3}{8}$ + x = $\frac{5}{16}$

x = $\frac{5}{16}$ - ( $-\frac{3}{8}$ ) = $\frac{5}{16}$ + $\frac{3}{8}$ = $\frac{5 + 6}{16}$ = $\frac{11}{16}$

x = $\frac{11}{16}$

Answer 2

-3/8=5/16

put x after -3/8 to find 5/16

-3/8+x=5/16

find x

move -3/8 to the other side

sign changes from -3/8 to 3/8

-3/8+3/8+x=5/16-3/8

x=5/16-3/8

find the common denominator which is 16

multiply by 2 for -3/8

(-3)(2)=-6

(8)(2)=16

x= 5/16--6/16

negative sign and negative sign= +positive sign

x= 5/16+6/16=11/16

answer: x=11/16
